Apple today seeded build 13E19 of OS X 10.9.4 to developers, just over a week after seeding the second OS X 10.9.4 beta and more than a month after the public release of OS X 10.9.3, which included enhanced support for 4K displays and syncing improvements.
The beta is available through the Software Update mechanism in the Mac App Store and should be in the Mac Dev Center shortly.
It remains unclear what improvements the 10.9.4 update will bring to Mavericks, but it is likely to include bug fixes and stability enhancements. Apple is asking developers to focus on Graphics Drivers, Bluetooth, Audio Drivers, Finder, App Store, and Safari.
Update: The new build is now available in the Mac Dev Center.

people who have zero understanding of what dev. preview means.
these releases aren't meant to be stable system wide, necessarily. they're meant to preview, test, develop new technology implementations and/or "improvements" over older technologies.
if you didn't get your dev. previews via torrent sites, you'd actually understand what dev. preview means.
lol
you can keep your mavericks or whatever OS you bloody well want. it will eventually become deprecated. However, really, that won't necessarily matter depending on how satisfactory your OS + software solution is for the implementation of the desired end result your needs indicate.
I want stability. Something that's been lacking in OS X in recent years.
A new OS per year is ridiculous.
I'd like it if companies actually FIXED existing software instead of just rapidly releasing new software.
The existing stuff isn't fixed, and the new stuff introduces new bugs. Those new bugs won't get fixed, because they will just release a newer new product instead.
Bluetooth sometimes just "dies" on 10.9. Apple Mail has lots of issues in 10.9. Will these be fixed with 10.9.4? Who knows. Are they fixed in 10.10? Who knows.
And yes, I upgrade my MacBook every refresh cycle, so a two year old MacBook would be used as a doorstop in my house.
What has been unstable about it? I've been running Mavericks as soon as it came out and not a single kernel panic, little to no problems with Safari and pretty much everything working as planned (I guess not using gmail also helps the situation).
Why is it ridiculous? it is nothing less than a rolling release with features being added only when mature and taking bite size changes rather than trying to cram a **** tonne of features into a single release then running around like headless chickens for the next 6 months fixing bugs.
